The calculation method to determine the correct number of digits (exponents) is as follows: Any number can be expressed in terms of an exponential expression as follows: Assume A = a x 10", B = b x 10Y, and C = c x 10' • (10 > a, b, c >1) Multiplication: Thus, the product of A and B is relative, for calculation of the number of 10, multiplied by C (= c x 10'). Hint for example, "90" assumes any values that are the n-th power of digits rn Any value on the logarithmic scale is represented by itself (9, 900, 9,000 ...). z = x+y (if c a, b) z=x+y+ 1 (ifc
